Theodoros the Doorkeeper

Theodoros the Doorkeeper (died 431 BC) was a Greek mercenary during the Peloponnesian War.

Biography
Theodoros was once responsible for protecting the doors of Potidaea from a Persian siege. When monstrous waves came over those fighting, it was said that Theodoros woke up far away from the city he was supposed to protect. He stayed away from Potidaea forever, lest he return only to be exiled for his failure. In 431 BC, he was hired to assassinate the mercenary Kassandra of Sparta, and he tracked her down to a rooftop in Corinth, where they battled. Kassandra succeeded in slashing Theodoros, who fell from the roof to his death.
